Description
[technical field]
The present invention relates to a kind of industrial control system, relate in particular to a kind of Fingerprint Encryption Safe Industry Control System.
[background technology]
Industrial control system is mainly used in the process control in industrial technology transformation and the industrial automation, and it is applicable to every field such as communications and transportation, Ferrous Metallurgy, electricity power, industry light industry textile industry, petrochemical complex, industrial furnace, machine-building, medicine equipment, medicine food, military project, building materials, teaching.
It is 02117200.5 that a kind of industrial computer can be consulted application number, and denomination of invention is the Chinese patent of dual bus Industrial Control Computer and control method thereof, but the same cipher mode that all do not adopt with existing most of industrial computers of the disclosed industrial computer of this patent.The utilization of encrypting fingerprint mode on industrial computer now also seldom, even and have application all to be confined to Authority Verifications such as opening of file, that is to say, whole industrial computer (comprising hardware and BIOS) does not change, just adopt general fingerprint capturer, just can realize according to different operating system and application collocation corresponding driving program.
Existing industrial computer powers up start-up course: at first industrial computer is called in internal memory and operation to BIOS (Basic Input or Output System (BIOS)) automatically, just can enter system by startup password verification (it is an option, is selected by the CMOS parameter).The problem that this type of start-up course exists is: by to the CMOS power down process, just can remove cryptographic check, need not like this to verify that just can enter system normally moves, not antitheft, the anti-illegally function of start truly.In addition, password may be revealed, and problem such as is stolen and forget by the people.
Illegally opened for the cabinet that prevents industrial computer, cause the loss of hardware or information, usual way is to adopt common mechanical lock with this Machine case lock, but the key storage difficulty, and easily lose or imitated; Secondly, when cannot keep whom once had open case record; In addition, when key storage power is transferred, for safety, must change lock etc.
[summary of the invention]
Technical matters to be solved by this invention is to provide a kind of BIOS by the existing industrial computer of modification, and the Fingerprint Encryption Safe Industry Control System that adopts fingerprint to encrypt.
For realizing purpose of the present invention, the technical solution adopted in the present invention is: a kind of Fingerprint Encryption Safe Industry Control System is provided, it comprises industrial computer, this system also comprises the finger print acquisition module that is connected with this industrial computer, and the fingerprint that this industrial control system received is to send instruction by this industrial computer to gather for this finger print acquisition module; This industrial computer also comprises the BIOS with fingerprint processing capacity, this BIOS with fingerprint processing capacity is the BIOS that integrates standard BIOS, fingerprint identifying module, fingerprint database and main management module, this fingerprint identifying module is that eigenwert is handled, extracted to the fingerprint image that this finger print acquisition module collects, and be saved in this fingerprint database, or judge the fingerprint recording whether coupling is arranged in this fingerprint database; This main management module be included as enter CMOS be provided with provide safeguard protection advance CMOS be provided with authentication module, for enter system provide safeguard protection enter the system verification module and authority is provided with module.
This BIOS with fingerprint processing capacity comprises that also press-key lock opens module, and the lock that this press-key lock opens module opens process and may further comprise the steps at least:
A. the fingerprint input causes interruption, enters press-key lock and opens service routine;
B. call the fingerprint identifying module;
C. judge whether to press-key lock opens fingerprint, if, then enter steps d, if not, then enter step g;
D. judge whether to be keyboard state;
E. if need to open, then open keyboard interrupt, the button service is provided, enter step g then;
